Quelqu'un d'autre

I have just started a new book (of note, for the sheer pleasure of reading) in which the main story line is a meeting of two 40-year-old strangers and the bet they make that in 3 years, these two men will become someone else, ie: the person they have always wanted to be, despite having so many years behind them, and so many things already 'given' in their lives.

After many months, grueling interviews and exams, administrative b.s. to boot, today, I finally walked into the museum as an employee. Hector at security (I've come to recognize him) asked me who I was there to see; I told him "Today, I start working". He looked at the list that told him what key he would need to open the corresponding coded box. From said box, he pulled out a large keyring (with 3 similar large keys, a small one, and a magnetic one), handed it to me, and bid me goodday.

The first key opens my office, a spacious work/study space on the third floor which I will share with 4 others. Large desks, computers, books, and a billboard with a child's doodle that told me this was a great environment. The second (similar, but shorter) calls the elevator (no buttons exist, security is airtight - thus the magnetic key). The tiny one opens a secret lock at the bottom of an invisible door in an exhibit wall on the fourth floor, which swings open to expose a veritable cabinet of wonders (it is an arts and crafts haven, I kid you not, this would have been Martha Stewart's dream room if she was 10 years old). The last key, which is almost identical to the first, is a mystery.

I have dreamed of working in a museum for what seems to be forever but is realistically 12 years. I work in a museum now. After many detours, and many attempts at finding my wee place in this huge world (and I found some pretty great places, but, somehow, they just didn't fit), I feel I have found my new home, my new life. There are so many things I could tell you about my first day. But, this is what is essential: I work in a museum now.
